Bullet-resistant glass is primarily made of which type of glass?

Bullet-resistant glass is primarily made of laminated glass, which is constructed by layering multiple sheets of glass and interlayers of polymer or resin that provide increased strength and impact resistance. This construction allows it to absorb and dissipate energy from bullets, making it effective in preventing penetration. The layers of glass, combined with flexible interlayers, create a composite that can withstand ballistic threats better than standard types of glass.

Reflected glass and plate glass do not possess the specific properties needed for ballistic resistance. Plate glass is generally used for applications where safety and security are not paramount, while reflected glass serves more decorative purposes and does not provide any enhanced protection from bullets. The choice of laminated glass for bullet resistance highlights the importance of advanced materials engineering in security applications, demonstrating how the interaction of layers contributes to overall performance against violent impacts.
